干湿纺PAN纺丝溶液的制备及其性能研究

STUDY ON THE PREPARATION AND PROPERTIES OF PAN SPINNING SOLUTION IN DRY-WET SPINNING

对以硫氰酸钠（NaSCN)水溶液为溶剂，分子量在８－１１×１０^4适合干湿法纺丝的聚丙烯腈（ＰＡＮ）纺丝溶液的制备工艺及纺丝溶液的流变性能进行了深入的研究，为纺制高性能AN碳纤维原丝提供了实验依据。

The technoiogical conditions of producing polyacrylonitrile spinning solution which molecular weight is between 80,000 and 110,000 are investigated.The properties of spinning solution are discussed.
